Vershun’s Brain Dump

So 3-4 years ago I picked up a really neat book on Swarm Intelligence and in it there were a few pages on the Adaptive Culture Model.  I really liked the concept (algorithmically simple and pretty) so I coded up a quick and dirty OpenGL app for it.

Well, for whatever reason, I thought of it a couple days ago and took a day off doing actual work to play with ACM in Flex.

Quick concept rundown.  So basically (from what I remember, don’t quote me) the adaptive culture model describes how information is spread throughout a population, specifically beneficial traits.  I guess an example of this would be success and proximity.  You notice a neighbor being successful, so you incorporate some of their traits into your life in hopes of you being more successful.  This goes from neighbor to neighbor until the successful traits are assimulated into the whole population.  Geography is just an example.  This can also model information spreading through virtual networks and other such fun stuff.

I implemented a quick and dirty presentation of this concept in Flex.  Success is rated by closeness to the target color you choose.  When you click on a couple squares it randomly checks a neighbor to see if it is more successful.  If it is, the neighbor assimilates one of its neighbors traits, which in this case is randomly either the red, green, or blue component.  If the square updates it notifies its neighbors of the change and they go through the same process.

You can change the color while the program is running if you feel like it.  There’s a lot more stuff that’s easily configurable but I got bored of this and am setting it aside for a while.  I’ll release the source when I come back to it later.

It might take a few clicks for the process to start.  Just select your color and keep clicking; when the queue starts filling up you’ll know.

As few of you are aware, for the past many Mondays I have been playing coed volleyball with a few high school buddies on a team called the Guppies.  For our last game we went out to celebrate the season with some Dairy Queen.  ”Celebrate,” might be a misleading term; we lost every single game we played.  It was less of a victory celebration and more of the kind of celebration one might have when being released from torture.  If you’re wondering, yes I have thought about it, and after deep self-analysis and reflection I have decided that sucking at volleyball is slightly more gay than just playing it.

Good things did come out of it, though.  Like plans for our new movie: Stem Cellz, which features a killer fetus that lassos its victims with its umbellical cord.

He Will Defetus All

We have a few good scenes for it too, but I’ll let them be surprises to you when it hits the big screen.

For production inquires or any other sort of interaction that will land us free money, please contact me.

… Tinkerbell?

Hey Tink!  Where are you hiding?!

FAT.

Fin.

Well it’s been forever since I’ve written anything and for some reason I keep getting returning hits so I assume you people want something from me.  So here’s my boring quick-and-dirty post about my life and then things to expect from this site in the future.

For those of you unfortunate enough to talk with me during my existential/quarter-life crisis; it’s over.  I’m now a Nihilist for the most part and I’m loving every second of it.  I love to argue so losing my Athiestic beliefs have opened up a whole new range of debating: specifically the validity of math and science.  I’ve found that by believing in nothing I’m open to experience anything and that has changed my entire perception of existence.  So uhhh… I’m happy and stuff I guess :-B

So I have a couple of jobs now.  Working at ClickFox doing Flex and Java which keeps me busy.  Also working on a site called Vindogle, which should be up fairly soon.  Other than staying busy all the time I have a wonderful gal that I’m quite fond of and I’m excited to finally see Dougie in Paraguay.

OK so things coming sometime this year to this site because they’ve been on my list for a while.  I have a few articles that are quarter to half written that I never got around to finishing; I’ll do that.  Also expect some sort of Flash-based data visualization for decentralized distributed computing (that one might take a hot minute).

Anyway, I promise I’ll keep up on this more when I have free moments.

Made a quick and dirty program that I ran last night.

So it sends a request for a “work unit” on a different server I have running a PHP script that builds some simple XML that looks something like:

<assignment>
<type>MD5</type>
<hash>6ded1c8c8b157a391e618ca39eb11e39</hash>
<prefix>Ab$x</prefix>
</assignment>

The program grinds through building MD5 hashes using the prefix and the next 2 characters.  Since this was just a test I’m only testing 126 characters so each work unit generates 15876 MD5 hashes and compares it to the target hash defined in the XML.

I made it so it’ll never find the hash because I wanted to test full work unit work so after it failed to find a match it returns its results to the server and requests a new assignment from the server.

Rinse.  Repeat.

So I got 57 hits during the testing phase with a return of 1128 work units.  This is roughly 18 million MD5 hashes tested.

I’m probably not going to pursue the MD5 collision thing (there’s much better ways of finding collisions instead of just brute forcing it anyway), but it’s an example of how hidden Flash applications can be used to put your traffic to work.

OK so I was going to just get rid of this blog but for whatever reason it has a PR rating so I might keep it around.  I’m definitely going to be changing quite a few things around here after I finish up the 3 projects I have queued up.  This blog will be moved to blog.vershun.com.  I’ll probably stop doing posts with any sort of substance (there’s pretty much none of that already) and instead become a lot more project-oriented, which is what vershun.com will be about.  This blog will truly be used as an outlet for my weird,which was its original intention (see identifying a zombie, smoking, and mediocre sex guide for more details).

BUT since I have a new server and haven’t posted in a while, here’s some random pictures.  I’m posting them just cause I’ve been playing with PS recently and have really nothing else to post right now.  Plus there’s not enough pictures on the internet yet.

The Badlands in South Dakota

The shores of New England are far cooler than beaches

These things are horrifying. There's no zoom on this but I was sure as Hell in my car at the time.

What's better to do in Salem than check out graveyards and abandoned buildings?

Lauren and Dave in Moab. Sheer cliff on all sides but back.

Through New Hampshire during autumn was the best drive I've ever taken.

Peruvian pelicans with a predisposition to petulance.

Bad picture but two of the best and brightest people I know, love, and miss. Amateur caving in Cusco.

Leaving the peak of Mt. Bierstadt, Colorado.

I might post again soon I have a few things I want to write I just haven’t gotten around to them.

It had been a long day.  Long, LONG day.  When Laura and I got back to her apartment we decided to call it a night since we both were exhausted.  “I should have a cig before we crash out,” I had said.  Stupid.

So Laura and I are joking around, as per the usual, and she said something particularly funny which gave me a bit of a kneejerk reaction.  I wish I could remember the joke but I was busy putting my right foot down onto air.

The fences around Brooklyn are ornate and beautiful.  They’re also hard.  And sharp.  If you happen to be laughing at your friend’s joke and fall onto one of them, it hurts.

Fences and gravity in cahoots against my giggles.

Now, it just felt like I got the wind knocked out of me, so when Laura yelled “OH MY GOD ARE YOU ALRIGHT?” I laughed and said I was fine.

“No you’re not… you’re bleeding.”

The feeling you get when you look down and see blood spreading through your shirt could probably be best described as “unnerving.”  I applied pressure for a few seconds until I realized that it wasn’t too bad of a wound.  My breathing was fine, heart was intact, and I didn’t have an iron rod through my body.

Holla at a sternum.

So Laura was about to get an ambulance but we decided we’d just cruise instead; no point in spending money for an ambulance and it was such a nice night.

I made her take a picture with me before we set off.  If she looks uncomfortable it’s because she is.

We go to the first hospital that my GPS finds, which is a mile away and was some random Brooklyn hospital.  When we get there we fill out a computer touch screen asking me my name, age, and the problem, which Laura awesomely put “Hole in chest bleeding.”

I was 2nd in line.  Oh well.

Everyone called my doctor “Dr. Spikes” in the acute ward because of his spikey hair.  I thought it was ironic.

Worst.  Hospital.  Ever.  Took them about an hour to even see me once I got the stretcher thing.  Threw a bandage on it and IV’d me up.  The Jamacan nurse was awesome and kept calling me the “luckiest guy alive.”  When I left we hugged; I was her favorite patient of the night.  She was my favorite Jamacan ever (much nicer than experience with one waiting for the Chicago L who made a slicing-your-neck motion).

Dr. Spikes wanted a CAT scan of me, “just to be sure.”  So I drank a shitton of disgusting liquid and then got to wait around another 2 hours while they “prepped” (drank, I assume).

The CAT scan was pretty sweet.  When they put the activator liquid in they said, “You might feel some warmth in your arm and have a metallic taste in your mouth.  That’s normal.”  By no means was that “normal” to me but it certainly is kickass.  They should have continued on though and said, “the warmth will spread throughout your body and eventually hit your pelvic region.  This will make you feel like you just shit and pissed yourself and you’ll have to lay awkwardly for another 2 minutes until you can get up and survey the damage.”

I didn’t shit myself.  Win.

So the scan results were suppost to take “30 minutes.”  I was finally released 2 hours later.  It wasn’t so bad though because Dr. Spikes let me go outside to smoke, which I was a little weirded out about since the CAT scan was supposed to be looking for if I was bleeding into my lungs, but whatever… he’s a doctor.

Laura was hilarious the entire time and God bless her little heart she stayed with me in the hospital throughout the entire 5 hour ordeal.  She didn’t even want to come outside for that initial smoke in the first place.

Snapped when we got back:

And that was my night.  Missed my flight to San Francisco in the morning for my cousin’s wedding.  Suck.

Were pretty awesome imho.

That is all.

I was staying at this place in Toronto that offered furnished temp living or whatever. Essentially it was a hostel with private rooms and there were about 8 other guests.

The owners were a 50-something Asian couple that were cute as a giggling puppy.

Anyway.

So I’m mildly intoxicated and the internet goes out. This makes me angry.

I scour the house looking for the wireless router and I don’t see anything. This is at 2 AM or so and the whole house is asleep except for 1 dude who didn’t speak any English.

So the internet is down. In desperation I start searching cabinets in hopes that they just threw the router in there. Right outside the kitchen I scope this out:

So I figure it has some trinkets or hanging lanterns or whatever the hell people put in cabinets. When I go to open it I’m greeted not with shelves and a wall, but leethax:

As I ducked through there was a separation to the left and a little (tiny in every respect, maybe 3 1/2 foot ceilings too) hacklab, complete with cheap folding chairs, gutted computers, routers, switches, and just a hefty sized chunk of awesome.

Anyway, thought it was cool.
